myd 2o @ige Je KITCHEN RANGE.

To all whom t may concern.'

Be it known that I, AxnL EUGEN Lnnn anne, a subject of the King ofSweden, and resident of Sundsvall, in the Kingdom o'i Sweden, haveinvented certain new and useful improvements in Kitchen Ranges, of whichthe following is a specification, reference being had therein to theaccompanying drawing.

The present invention relates to a kitchenrange with the lireplacelocated over the oven and which is so arranged that the fluegases arecarried off on both sides over the walls of the lireplace and downwardsalong said walls and the two side-walls oi the stove and further underthe bottom of the latter to an outlet 'for the flue-gases. According tothe presentinvention the range is provided with controlling means,through which the range may be so set, that for instance when the rangeis used for cooking the heat is concentrated under the cooking utensils,and over and around the oven when baking. In order to obtain a draughtwhich is as uniform as possible in all parts of the Fluss the outlet forthe flue-gases under the oven is given a special form, suited for thepurpose. For utilizing the heat of the escaping flue-gases the range iscombined with a water-heater, which is so arranged, that the {lue-gasessweep around it on all sides.

A range according to the present invention is shown in the accompanyingdrawing, in which Fig. 1 is a vertical section at right angles to thefront face of the range. Fig. 2 is a vertical section on the line A-B inFig. 1 and Fig. 3 is a horizontal section on the line C-D in Fig. 1.

The fireplace 2 of the range 1 is located right above the stove 3 andboth are so arranged in the range, that a space will be providedeverywhere between them and the walls, top and bottom of the range. Inthe embodiment shown the fire-place is provided with an auxiliary top 4,in which openings 5, 6 are located right under corresponding cookingholes in the top 7 of the range. Said arrangement is done in order toconcentrate the fire under the cooking utensils. The flue-gases escapeat both sides over the walls of the fire-place and downwards along thesides of said fireplace and the stove and 'further under the stove 3 toan outlet 30 in the bottom of the Specification of 'Letters Patent.

range. A series of openings is provided in the upper part of each one ofthe sidewalls of the lire-place. A downwards inclined screen 9 extendsabove each one of the walls, said screens being extended all along thefireplace.- Dampers 10 are pivotally connected to the free edges of saidscreens orthe screens themselves are made in the form of dampers. Thedampers of the one or.k the other kind may be swung in against the wallof the oven or out against the wall of the range by means of a shaftwhich extends through the latter wall. In the former case the flue-gasesare forced to pass through the openings 5 and 6, at which the lire isthrown right up and parted against the bottoms of the cooking utensils.In' the latter case the flue-gases are forced to escape from thefire-place 2 through the openings S, at which they are guided right downagainst the rstove 3 by means of the screens. By the said arrangeL mentit is made possible to concentrate the heat for example when cookingunder the top of the range and when baking over and around the stove.

Of the above mentioned openings 5, 6 in the top of the lire-place thelatter may be closed by means of ak cover 12, when one cooking-openingonly is used. The cover 12 is hung up in a link 13, made of a fiat bariron or the like, said link being carried through a slotin the cover 14,which covers the cooking-opening. `At the top said link is provided withan eye 15, in which the hook can be inserted in order to lift up andremove the covers 12, 14 when this is required. In order to keep thecover 12 in its raised position when the cover 14 remains lowered thelink 13 is at the bottom provided with recesses, so that a thin stem 16is formed, by means of which the link `and the cover 12 can be turned intheir raised position and the parts of the link which overlap the stemcan be supported by the cover 14. Obviously thereplace opening at thefront may also be provided with a cover arranged in the same way. Underthe inner portion oit' the grate 17, which in the embodiment shownconsists ol a grating 18., is provided a slidable damper in the torni ofa corresponding grating 19, by means of which the openings in the gratecan be closed. vSaiddamper is moved by means of a bar 20, which passesshut, whereby the combustion takes placeonly in the fore portion of thefireplace.

f The chamber 21, located under thebottom of the range is providedwithtwo outlets 23, 24 for the flue-gases or' which the for mer leadsdirectly to the 'flue in the masonry of the range and the latter to achamber at the side of the range, which cham ber communicates with theflue in the rangemasonry through a passage leading from the opening 26in the upper portion of one of the side-walls of the latter. A waterheater is provided in the chamber 25 in such a way'that the flue-gasessweep around it on all sides. may be usedf'or different purposes. Thechamber `21 is partitioned by means of a wall 22, runningfalongtheopening 7 which extends to the same level as the inner edge of theopening 24. Through a turnablc damper 28, which is operated `from theoutside, the flue-gases may be led by means of the wall: 22 either tothe outlet 23 or to the chamber 25, in the latterl case for heating theelement 27. In the drawing the damper'is shown with full lines set forthe latter purpose and with dash-lines set in the opposite direction.The wall 22 obviously brings about a reduction of the draught at therear portion of the chamber 21. In order to make the draught as uniformas possible in all portions of the lues in the range the edges of theopening` diverge backwards at an angle suited for the purpose. i

Having now described my inventiomwhat I claim as new and desireto'secure by Letters Patent is:

1. Kitchen range, provided'with a {irepltace, located over the stoveland which is sovarranged that the flue-gases are carried ott at bothsides over the walls of; the'iireplace and downwards along said wallsand the two side-walls of the stove and 'further under the bottom of thelatter to an outlet for-the flue-gases located at the latter place,characterized thereby that one or more openings (8) are arranged in theupper portion of each one of 'the sidewalls, above which openingsadjustable screens or stationary screensprovided with dampers (10)extend from said walls, by means of which screens the room located onthe sides of the 'tireplace can be screened off in such a way, that theflue-gases either are forced to 'How over the walls or' the fire-placeup against the top of the range or through the openings in the `walls ofvthe ireeplace right down over-'and around the oven, in order to obtaina more advantageous concentration ot' the heat.

2. 'Kitchen range according to claim 1,
